ROOF-CARLINE.

SPECIFICATION forming part of Letters Patent No. 649,171, dated May 8,1900.

Application filed December 29, 1899. Serial No. 741,934 (No modell Toall whom, it may concern:

Be it known that I, GEORGE B. MALTBY, of Grand Rapids, in the county ofKent and State of Michigan, have invented a certain new and usefulImprovement in Roof-Carlines, of whichimprovement the following is aspecification.

The object of my invention is to provide a roof-carline, speciallyapplicable for usein the framing of railroad freight-cars, which shallembody the features of strength, lightness, and economy of constructionand present simple and effective means for connecting and firmlysupporting the ridge-pole and purlins in their respective positions inthe roof structure.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view inelevation,showing slightly more than one-half in length of aroof-carline embodying my invention; Fig. 2, a plan or top view; andFigs. 3 and 4, transverse sections at the lines a, a and b b,respectively, of Fig. 1.

In the practice of myinvention I provide a roof-carline which is formedof sheet or plate metal, preferably by being pressed or shaped in a dieor mold. The body 1 of the carline is integral and is made of U orchannel shape in transverse section, its top being open and its sidemembers gradually diminishing in depth from its middle toward each ofits ends. It is also downwardly inclined from its middle to each of itsends at such an angle as may be adapted to impart the desired pitch tothe roof. The ends of the carline are turned upwardly similarly to theside members, forming bearing-faces which abut against the ends ofrecesses in the side plates 2 of the carframe, in which the end portionsof the carlines are fitted, and are-secured thereto by bolts 3 in theordinary manner, and the rid gepole and purlins rest in recessed seatsin the carline. The channel form of the body enables it to be made lightin weight, while being of ample strength to act as a firm transverseupper brace to the car-frame and a substantial support to thelongitudinal members and covering-boards of the roof.

In order to provide suitable bearings for the ridge-pole 4 and purlins 5of the roof, the

metal of each of the side members of the body is turned outwardly at itstop at the middle of the-body and at suitable distances therefrombetween the middle and the ends, so as to form pairs of wings 6 ofchannel-section, in which the ridge-pole. and purlins are fitted and towhich they are secured by bolts 7, passing through perforations 8 in thewings. It will be'seen that the wings 6 not only provide amplebearing-surface for the longitudinal roof members,which they receive andsupport, but also enable the latter to be firmly and convenientlysecured to the carlines and held at their proper distances apartthroughout the length of the roof. WVhile the wings 6 are preferably, asshown, formed on each of the side members of the body, their employmentin pairs is not an essential of my invention, and they may be providedon one side member only, if preferred.

The practical advantages of strength, lightness, and facility ofapplication in ordinary car-framing which are presented by myimprovement will be obvious to those familiar with railroadconstruction, and it will also be apparent that it may be employed inconnection with a roof of any desired type.

I claim as my invention and desire to secure by Letters Patent- 1. Asheet or plate metal roof-carline having a body of U or channel section,the side members of which gradually diminish in depth from its middletoward its ends,and having closed ends constituting bearing-faces,

2. A sheet or plate metal carline having .a body of U or channelsection, the top of which is open and the side members of which grad-.

ually diminish in depth from its middle toward its ends and are providedwith recessed seats for longitudinal roof members. A 3. A sheet or platemetal roof-carline having an open-topped body of U or channel section,and having outwardly-extending lateral wings, of channel section, forthe support and connection of longitudinal roof members.

4. A sheet or plate metal roof-carline hav 7 ing an open-topped bodyof Uor channel sec tion and having the metal of its side members turnedoutwardly at top, at its middle and at points between its middle andends, so as to present pairs of lateral wings, of channel-section, forthe support and connection of a ridge-pole and purlins.

5. In a car-frame, the combination of recessed side plates, plate-metalroof-carlines, pressedinto channel-section with closed ends,

and having their ends fitting in and abutting against the ends of therecesses of the side plates, bolts passing through the bottom mem-
